If you need to flash an original firmware it will do the job. Just download proper version.

@vladimir-kuznetsov, I have downloaded the correct Full-ROM (OTA) package and when I use XiaomiADB, sideload starts and ends within a millisecond with error "ERROR: Sideload error -> adb: failed to read command: no error".

If possible, can you help me with that? Thanks.

You need to switch your phone into recovery mode (hold Volume Up during reboot) and select " connect to mi assistant". Then connect to PC and run adb sideload. In my case it reported some issues but flashing started. The phone should reboots by itself after everything completed.
If this does not help I gues you need to try Emergency recovery but I never try it.
